3 1 DESCRIPTION The LSX connector module is an LGX compatible, rack-mounted termination panel that provides a physical interface between fiber optic cables (terminated on the rear side of the bulkhead) and patch cords (terminated on the front). In a typical application, cables from transmission facilities are patched to fiber optic terminal equipment. The LSX connector module may be used in either an interconnect or cross-connect configuration, in either single mode or multimode applications, and with either stranded or ribbon cable. The cables may be either Intrafacility Fiber (IFC) or Outside Plant (OSP). The LSX connector module is available with 72, 96, or 144 fiber positions. Figure 1 shows the main external features of the 72-position module. Other modules are the same except for number of connectors and panel height. The main features are (from top left counterclockwise): LGX COMPATIBLE CHASSIS BULKHEAD CONNECTOR PACK PATCH CORD GUIDE MOUNTING BET REMOVABLE FRONT COVER PATCH CORD DESIGNATION CARD RADIUS LIMITER B Figure 1. Main External Features of LSX LGX Compatible LSX Module is of solid metal construction and painted putty white. The 72- and 96-position LSX connector modules have a rack height of 7 inches (17.8 cm) and a maximum of nine of these modules may be installed in the LGX frame. The 144-position connector module has a rack height of 9 inches (22.9 cm) and a maximum of seven of these modules may be installed in the LGX frame. Bulkhead holds the pass-through adapter/connectors that provide the physical interface between cables and patch cords.

If loaded with connector packs, it may also be loaded with a factory-terminated cable stub. If the module was not shipped with a factory-terminated cable stub, a cable clamp (provided with the unit) must be installed. The cable may or may not be already broken out and preterminated. If it is not, cable preparation is required as part of installation. Depending on how the module being installed was equipped, select from the procedures below. Procedures are provided for installing the connector module, installing adapter packs, breaking out a cable, installing a cable clamp, and routing a cable within the module. Only the first procedure is required if the module was pre-terminated in the factory. 3.1 Installing the Connector Module The LSX connector module is designed to be installed from the front side of the rack. To install the connector module: 1. Determine the mounting location and rack width. For a 19-inch rack, remove the two mounting brackets and re-install them using the 19-inch orientation (refer to Figure 3). For 23-inch rack, install the chassis with the mounting brackets positioned as shipped. 2. Secure the mounting brackets to the rack front flange using six #12-24 mounting screws, as shown in Figure 4. Note: If LGX jumper retainers are being used, remove them and reinstall them with the chassis as shown in Figure 4. The jumper retainers are not an ADC product. 3.2 Installing a Connector Pack To install a connector pack, press the connector pack firmly into the desired slot, pressing the plunger-expanders into the mounting holes. See Figure 5. Page 6

Route the removed cable to the spare cable bundle and secure with tie wraps or lace as required by local practices. Page 13

14 4.3.2 Cable Removal Procedure 1. Locate the quad cable to be removed from the cable bundle in the overhead racking. Follow the cable to the breakout point in the module and verify working and spare fiber pairs. 2. Using a light source, verify the spare fibers at the equipment locations specified. Disconnect the working fibers from the equipment and install dust caps. 3. Disconnect the working fiber pair from the adapters and install dust caps on the connector ends. 4. Remove the working and spare fibers from the cable retainers in the module. See Figure Cut the strain relief holding the cables in the vertical cable guide but do not remove the strain relief. 6. Attach the end of a new strain relief to one end of each cut strain relief and use the cut strain relief to pull in the new relief around the cable bundle. 7. Repeat steps 5 and 6 for each strain relief supporting the cable bundle. 8. Remove the quad cable from the cable bundle. 9. Tighten the new strain relief(s) around the cable bundle Cable Install Procedure 1. Label the ends of the new cable in accordance with local practice. 2. Cut the strain relief holding the cable bundle to the rack but do not remove the strain relief. 3. Attach the end of a new strain relief to one end of each cut strain relief and use the cut strain relief to pull in the new relief around the cable bundle. 4. Repeat steps 2 and 3 for each strain relief supporting the cable bundle. 5. Insert the quad cable into the cable bundle. Connect the working fibers to the equipment. 6. Route the quad cable through the radius limiters and retainers on the module and separate the working and spare fiber pairs. See Figure Remove the dust caps from the working fiber pair, clean the end face of the connector, and attach these fibers to the module connectors. 8. Remove the cable slack from the working and spare fiber pairs on the module and route the excess into the overhead cable bundle. 9. Tighten the new strain relief(s) around the cable bundle. Page 14

15 5 PATCH CORD ROUTING Cross-connect jumpers on the LSX modules and LGX frame must be carefully dressed to ensure they are properly protected. 5.1 Patch Cord Routing Within the LSX Module Dress the patch cords vertically down the front of the connector pack on each module and then left or right through the guides and radius limiters on the LSX module as shown in Figure 14. CONNECTOR PACK PATCH CORD GUIDE C RADIUS LIMITER Figure 14. LSX Module Patch Cord Guides and Radius Limiters 5.2 Routing Patch Cords on the LGX Rack Patch cord routing should allow for a minimum of 6 in. (152 mm) of slack loop in the vertical trough. This loop aids in the tracing of patch cords and also facilitates removing a patch cord from the bundle. Additional fiber slack should be expected when installing a set of pre-connectorized patch cords. The following section provides the procedures for disposing of excess patch cord length when installing patch cords on a single stand-alone rack, between two adjacent racks, or between two non-adjacent racks in a lineup. Page 15

16 5.2.1 Cross-Connecting Within a Single Rack Cross-connecting within a single rack (Figure 16) may be required when facility and equipment terminations are intermixed. Use the following procedure to route patch cords within the same rack. 1. Loop the patch cord across the upper raceway. 2. Route one end of the patch cord down the left vertical trough to a module termination point. Route the other end of the patch cord down the right vertical trough to a module termination point. Under certain conditions, a patch cord may need to be terminated beyond the half-way point of a module with the other end routed to a termination on the same side of the module or a different module to ensure that the patch cord is properly suspended in the upper raceway. See Figure B Figure 16. Routing Patch Cords within Standalone Racks Page 16

17 3. Adjust the slack loops of each patch cord to an equal length and then dress the excess length behind the module guides and retainers All cross-connection routing within a single rack should be done with 5 meter (16.5 ft) patch cords. Shorter 3 meter (9.9 ft) patch cords can be used when both ends are terminated in the top half of the frame Cross-Connecting Between Adjacent Racks Cross-connecting between adjacent racks (Figure 17) is accomplished using the following procedure B Figure 17.Routing Specified Length Patch Cords Between Adjacent Racks Page 17

18 1. Terminate one end of the patch cord on the originating module and rack and then route the patch cords left or right to the nearest rack vertical trough. 2. At the destination module and rack, terminate the opposite end of the patch cord and then route the patch cords left or right to the nearest rack vertical trough. 3. Route the patch cord over the upper raceway or jumper support bracket to the adjacent rack. 4. Adjust the slack length at both ends of the patch cord to about equal length and dress the excess length behind the rack retainers and module guides. All cross-connection routing between adjacent racks can be done with 6 meter (19.8 ft) patch cords. Shorter 4 meter (13.2 ft) patch cords can be used when both ends are terminated in the top left of the frame Cross-Connecting to Non-Adjacent Racks Patch cords may be routed through upper or lower raceways to non-adjacent LGX racks in a rack lineup. As a general rule, patch cords originating in LSX modules located in the upper half of an originating rack are routed to the upper raceway. Conversely, patch cords originating in modules located in the lower half of an originating rack are routed to the lower raceway Patch Cord Length Selection The user must select the correct patch cord length based on the number of racks to be traversed, and which raceways will be used to route the patch cord. See Table 2. Page 18

20 Routing Patch Cords in the Lower Raceway Cross-connecting starting in the lower raceway can be accomplished using the following procedure (see Figure 18 and Figure 19). 1. Terminate one end of each patch cord on the originating module and rack and then route the patch cord left or right to the nearest rack vertical trough. 2. Route the patch cord terminated in step 1 down the left or right vertical trough to the lower raceway. 3. At the destination module and rack, terminate the opposite end of each patch cord and then route the patch cord left or right to the nearest rack vertical trough. 4. Route the patch cord terminated in step 3 up the left or right vertical trough and over the upper raceway as shown in Figures 18 and Insert the patch cords in the lower raceway between the origin and destination racks. Adjust the slack loops in the vertical troughs to prevent buildup within the raceway. ORIGINATING TERMINATION LOCATIONS DESTINATION TERMINATION LOCATIONS B Figure 18.

23 5.3 Mounting 144-Position Modules Adjacent to 72- or 96-Position Modules Lucent L6X fiber distribution frames with a depth of 12 inches (30.1 cm) are typically used to mount LSX 72-position or 96 position connector modules. When mounting 144-position connector modules, Lucent L6X fiber distribution frames with a depth of 15 inches (38.1 cm) are recommended to accommodate the additional cabling encountered with LX.5 connectors. If a 15 inch deep L6X frame is not available, use a rear duct extension kit (Lucent category #FEX1A-FB or equivalent) to extend the rear doors of the frame back. The new 15 inch deep frame will line up with any existing 12 inch deep frame as shown in Figure 22. In addition, the relative mounting locations for Lucent JR4A-1 and JR4C-1 retainer caps on the front of adjacent racks containing LSX modules of different heights will be skewed horizontally as shown in Figure 23. The degree of retainer misalignment varies with the number of modules used to populate the adjacent rack. 5.4 Installing Modified Cable Retainers for 144-Position Modules The existing cable retainers on the rear of each Lucent rack must be replaced with new, higher-capacity cable retainers when LSX 144-position connector modules are installed. Two new top cable retainers are available (ADC catalog number LSX-ACC001) to provide a left and right cable orientation at the top of each rack upright (see Figure 24). Similarly, the existing rear vertical cable guides mounted on the rack at the left and right of each modules must be replaced with new, higher capacity guides when the rack is configured with LSX 144- position connector modules (rear vertical cable guides included with LSX 144-position connector module). The new rear vertical cable guide is shown in Figure 25. Page 23
